Well, it sounds like the rumors of Stella McCartney's pregnancy are no longer rumors. Sources tell us that McCartney and her husband are expecting their third child in December of this year. Just seven months ago, Stella and her husband Sir Paul McCartney welcomed a baby girl. No news on the sex of the baby, however, sources tell us that Stella is in the process of choosing a godmother for baby number three. As a celebrity fashion designer, McCartney probably has a knack for decorating a nursery!
